Question

Given the system of equations 2x – 8y = 0 and –2x + 4y = –8, which statements are true? Check all that apply.

The x-variable will cancel when adding the system of equations.
After adding the system of equations, you get –12y = –8.
y = 2
x = 8
The solution to the system is (2, 8).

Answer 1

2x - 8y = 0

-2x + 4y = -8

------------------

-4y = -8

y = 2, so x = 8

The x-variable will cancel when adding the system of equations.

y = 2

x = 8
